1. Corrosion a
A) is defined by NACE International as the deteriora-
tion of a material, usually a metal that results from a
reaction with its environment.
B) is produced when acids dissociate , when cation
takes place
C) is the division of chemistry that deals with the trans-
fer of electric charge in chemical reactions

ode for the reduction reaction to occur
E) is equal to the reciprocal of resistivity.
